I-NTC & sensor yokushisa Imibuzo Nezimpendulo
Q：YiniNTC thermistor?Zikhona izinhlobo ezinjani?
Impendulo:Isici sokwehla kwe-resistance njengoba izinga lokushisa likhuphuka sibizwa ngokuthi isici sokushisa okungekuhle, i-thermistor esetshenziselwa ukukhombisa isici sokushisa okungekuhle ibizwa ngokuthiI-NTC thermistor (Negative Temperature Coefficient Thermal sensitivity resistor).
Izinhlobo ezijwayelekile zifaka: uhlobo lwe-single-end glass seal, uhlobo lwe-bead elinekhanda elincane elimnyama, uhlobo lwe-bead enameled wire, uhlobo lwe-bead small leather wire, uhlobo lwe-card point small black head, uhlobo lwe-insulating film, i-diode、uhlobo lwamandlakanye ne-chip resistor.
Umbuzo:Yiziphi izici zobuchwepheshe ze-NTC thermistor? Sicela unikeze izibonelo.
Impendulo:Imingcele yobuchwepheshe eyinhloko ihlanganisa: inani lokumelana elijwayelekile (5K/10K/50K/100K…), ukubekezelelana kwenani lokumelana (ukunemba)(1%/3%/5%/10%), i-coefficient yokushisa kwe-resistance (inani le-B) (3270/3380/3435/3470/3950/4000/4050/4500…), ububanzi bokushisa okusebenzayo (℃) (-30℃-105℃/-30℃-125℃/-40℃-250℃…), i-material constant, i-time constant…
Umbuzo:YiniI-B value ye-NTC thermistor?
Impendulo:Inani le-B liyinto engaguquki yezinto ze-thermistor ye-coefficient yokushisa (i-thermal index), iyunithi yi-Kelvin temperature (K). I-semiconductor ceramic ngemva kokushiswa okushisa okuphezulu ngokusebenzisa uchungechunge lwezinqubo zokucubungula yakha i-NTC thermistor chip ene-resistivity ethile, ifomula ngayinye kanye nezinga lokushisa lokushisa kunenani elilodwa le-B. Inani le-B le-NTC thermistor lihlobene ngqo ne-coefficient yokushisa yokumelana yomkhiqizo, okusho ukuthi uma inani le-B likhulu, i-coefficient yokushisa yokumelana nayo iyakhula.
Ifomula yenani le-B ye-NTC thermistor ithi: B=T1T2Ln(RT1/RT2)/(T2-T1) lapho i-B: inani le-B le-NTC thermistor, linikezwa umkhiqizi; RT1, RT2: inani le-resistance ye-thermistor lapho izinga lokushisa lingama-T1, T2; T1, T2: isikali sokushisa esiphelele.
Inani le-B le-NTC thermistor ngokuvamile liphakathi kuka-2000K no-6000K, kuye ngokwesimo sokusetshenziswa okuhlukene kungakhethwa inani le-B elihlukile. Ngokuvamile, njengomkhiqizo wokulinganisa izinga lokushisa, isinxephezelo sezinga lokushisa kanye nokuvimbela i-surge, kungakhethwa inani le-B elikhulu. Ngoba njengoba izinga lokushisa lishintsha, umkhiqizo onenani le-B elikhulu ushintsha kakhulu kunani lawo lokumelana, okusho ukuthi uma inani le-B le-NTC thermistor likhulu, lisebenza ngokuzwela lapho lisetshenziswa, futhi isikhathi sokuphendula siyashesha.
Q：UkuhlelaYiluphi ulwazi okudingeka lunikezwe uma kufakwa i-NTC thermistor?
A:Uma kunohlobo lokumelana oseluvele lunqunyiwe, kudingeka kwaziswe inani lokumelana,Inani le-B, ukunemba kanye nobude bokumelana okudingekayo kuphela; uma ungacaci uhlobo, kudingeka ukushisa okusetshenziswayo, indawo yokusetshenziswa kanye nenani lokumelana, inani le-B, ukunemba kanye nobude bokumelana okudingekayo.
Q：Isivinini sokuphendula se-NTC thermistor sishesha kangakanani?
A:Isikhathi sokuphendula sichazwa njengokufinyelela62% noma isikhathi esidingekayo ekushiseni okusha, futhi kungumsebenzi wekhwalithi. Uma isenzwa sincane, sisabela ngokushesha. Isenzwa esihlukile sabela ngokushesha kunesenzwa efanayo epakishwe ngaphakathi kwekhabethe lensimbi. Isikhathi sokuphendula esijwayelekile se-MF52 series NTC thermistor sensor singaphansi kwemizuzwana engu-15.
Umbuzo:Ama-temperature sensor enkampani yenu awuhlobo luni lwe-temperature sensor? Yiziphi izinhlobo ezikhona?
A:Ama-temperature sensor enkampani yethu amaningi angawohlobo lwe-I-NTC type temperature sensor, kuye ngendawo yokusetshenziswa kanye nesakhiwo, kukhona uhlobo lwepayipi eliqondile, uhlobo olunentambo, uhlobo lwe-flange, uhlobo lwe-bullet head, uhlobo olufakwe nge-epoxy resin, uhlobo lwe-lock plate terminal, uhlobo lwe-ABS plastic shell kanye nohlobo lwefilimu ongakhetha kuzo. Ngaphezu kwalokho, inkampani yethu inama-PT100/PT1000 temperature sensor, ama-DS18B20 temperature sensor, ama-thermocouple kanye nama-infrared temperature sensor.
Umbuzo:Ingabe ama-temperature sensor enkampani yenu akhona esitokweni? Ingabe asekela ukwenziwa ngendlela oyifunayo?
A：I-sensor yokushisa iwumkhiqizo okhethekile, izidingo zamakhasimende ahlukene ziyahluka, imikhiqizo ekhona manje iningi liwuhlobo oluvalwe nge-epoxy resin, ezinye izinhlobo zimbalwa.
Imikhiqizo yethu isekela ukwenziwa ngendlela oyifunayo, ama-thermistor okufanele asetshenziswe angakhethwa, futhi ezinye izingxenye ezingenziwa ngendlela oyifunayo zihlanganisa: ubude, usayizi kanye nokuma kwezingxenye zensimbi, uhlobo, ukucaciswa kanye nobude bentambo, kanye nokukhetha izinhlobo ezahlukene zama-connector.
Q：Uma kungacaci ukuthi hlobo luni lwe-sensor yokushisa okudingeka isetshenziswe, kungenzeka yini ukuncoma?
A：Lokhu impela, ngoba izinhlobo zokuxhumana ziningi, uma ikhasimende lingacaci, sizoncoma ikhasimende ngokusekelwe endaweni yokusetshenziswa kanye nezidingo ezikhethekile, ukuze ikhasimende lithole umkhiqizo owanelisayo. Ngaphezu kwalokho, singakwazi ukulungisa ukwakheka komkhiqizo ngokushesha ngokuvumelana nezidingo zekhasimende, sakhe umkhiqizo owanelisayo odingwa yikhasimende.
Q：Ingabe kukhona imikhiqizo ehlobene namandla amasha?
Impendulo:Amandla amasha bekuyinto edumile eminyakeni yamuva, kufanele kube khona emikhiqizweni yethu. Hhayi nje amandla amasha,Imikhiqizo esetshenziswa ku-3D printing nakwezinye izindawo nathi siyayisebenza, ibanzi kakhulu.

Umbuzo: I-R-T table ye-NTC thermistor ne-sensor yokushisa itholakala kanjani?
A： Yebo, umkhiqizo uzoba ne-R-T table ehambisanayo, futhi idatha yabakhiqizi abahlukene iyahluka ngokwayo. Uma udinga i-R-T table eqondene nomkhiqizo ungaxhumana nabasebenzi benkampani yethu ukuze uthole usizo.
Q： Ingabe inkampani yenu ingasiza ngokuklama umkhiqizo nokudweba imidwebo?
Impendulo: Yebo kungenzeka. Ukudweba imidwebo yomkhiqizo kudinga ukunikezwa kwedatha yezingxenye zomkhiqizo, okuhlanganisa into, usayizi nezinye izidingo ezikhethekile, futhi kudingeka imvume ekhethekile.
